Each well will be screened at the bottom using a maximum of 10 feet of slotted PVC casing with filter pack material placed between the borehole and screen. Above the filter pack, the space between the PVC casing and borehole will be sealed using bentonite chips. The surface completion for the 2-inch diameter wells will comprise 20 feet of neat cement placed between a 9-inch diameter borehole and 3-inch diameter steel casing. The surface completion for the 4-inch diameter wells will comprise 20 feet of neat cement placed between a 12-inch diameter borehole and 8-inch diameter steel casing.
